This, in effect, is the equivalent of deleting only residues 28 and 30 of the wild-type B chain. ; IPH PHENOL × 6 ZN ZINC ION × 2 CL CHLORIDE ION × 2 X-RAY DIFFRACTION X-ray crystallization conditions:VAPOR DIFFUSION, HANGING DROP;298 K;1:2.5 ratio of Zn2+ to protein monomer in 0.02M Tris-HCl, 0.05M sodium citrate, 5% acetone, 0.03% phenol, 0.01% zinc acetate, PH 8.0 Resolution 1.95 Å R-free 0.249
